Tsui; Silene potanini Maximowicz; S. tatarinowii f. albiflora (Franchet) Kitagawa; S. tatarinowii var. albiflora Franchet. Herbs perennial, finely retrorse-pubescent throughout. Roots yellowish, cylindric or spiniform. Stems ascending or supine, branched, sometimes with adventitious roots at nodes. Leaves lanceolate or ovate-lanceolate, rarely ovate, 2–5 × 0.5–1.5(–2) cm, both surfaces sparsely villous, margin shortly ciliate, 1- or usually 3-veined, base broadly cuneate or attenuate into petiole, apex acuminate. Dichasial cymes lax, broad. Pedicel 8–30(–50) mm, slender, pubescent; bracts lanceolate, herbaceous. Calyx tubular-clavate, 1.2–1.5 cm × 3–5 mm; longitudinal veins green, rarely violet, glabrous or sparsely pubescent; calyx teeth triangular, margin membranous, shortly ciliate, apex acute, rarely obtuse. Androgynophore ca. 4 mm, glabrous. Petals white, oblanceolate, claws not or slightly exserted beyond calyx, glabrous, exauriculate; limbs obovate, ca. 7 mm, shallowly bifid to 1/4 of limbs, each with 1 small linear lobe or slender tooth on two lateral lobes; coronal scales elliptic, margin entire. Stamens prominently exserted; filaments glabrous. Styles prominently exserted. Capsule ovoid or narrowly ovoid, 6–8 mm, shorter than calyx. Seeds gray-brown, reniform, ca. 1 mm. Fl. Jul–Aug, fr. Aug–Oct. • Brush, forested stony mountains, rock fissures; 800–2900 m. Gansu, Guizhou, Hebei, Henan, Hunan, Nei Mongol, Ningxia, Shanxi, Shaanxi, Sichuan. Species nos. 91–110 belong to an informal group that approximates to Silene sect. Cucubaloideae Edgeworth & J. D. Hooker. As circumscribed here, this is a distinct, probably monophyletic group characterized by more or less creeping habit and fleshy, fasciculate root tubers. The species of the “Cucubaloideae” group can be described as follows. Herbs perennial. Root tubers clustered. Stems diffuse, supine or ascending, branched. Leaves ovate to linear, 3- or 5-veined. Inflorescence a dichasial cyme. Flowers bisexual, erect. Calyx tubular-clavate or campanulate, closed in fruit, open at apex, longitudinally 10-veined, veins usually violet, usually coherent at calyx teeth. Androgynophore short. Petals red, rarely white, bifid, sometimes 1-toothed on each side; coronal scales present. Styles 3. Seeds reniform, with slight auricular pit, minutely tuberculate; raphe obtuse, rarely acute, minutely tuberculate or with spinose process. The group is distributed in China, the Himalayas, and Indo-China. Silene habaensis H. Chuang (in C. Y. Wu et al., Fl. Yunnan. 6: 837. 1995) probably also belongs to the “Cucubaloideae” group, but we have not seen any material. According to the protologue, it is similar to S. bilingua, but differs in having a tubular-clavate calyx and 2-lobed petals.
